New discovery at Jupiter could help protect Earth-orbit satellites
Radio waves accelerate electrons within Jupiter's magnetic field in the same way as they do on Earth, according to new research published in Nature Physics this week. The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting Earth-orbiting satellites. view more (2008-03-10)
NewsService Journaline: The Information Service for Digital Radio live at CeBIT
The new information service available for the digital radio systems DRM (Digital Rado Mondiale) and DAB (Digital Audio Broadcasting) will be presented at the BMBF booth. view more (2005-03-10)
Stable polymer nanotubes may have a biotech future
Scientists at the National Institute of Standards and Technology (NIST) have created polymer nanotubes that are unusually long (about 1 centimeter) as well as stable enough to maintain their shape indefinitely. view more (2006-02-03)
Medical Imaging with 'Swiss Rolls'
Under Strict Embargo for 19:00 London GMT/14.00 US EST Thursday 1 February A novel magnetic material developed by British researchers may lead to dramatic improvements in the performance of Magnetic Resonance Imaging (MRI) systems. Writing in the journal Science today they describe initial experiments confirming the exotic nature of the material... view more... (2001-02-01)
Housecat-sized Siberian tiger cubs get collared
Scientists from the Wildlife Conservation Society (WCS) and their Russian colleagues from the Russian Far East recently fitted three wild 40-day-old Siberian tiger cubs with tiny radio-collars, marking the youngest wild tigers to be tracked by scientists. view more (2005-10-26)
US satellite protection scheme could affect global communications
A proposed US system to protect satellites from solar storms or high-altitude nuclear detonations could cause side-effects that lead to radio communication blackouts, according to new research. view more (2006-08-15)
U. T. Dallas-led research team produces strong, transparent carbon nanotube sheets
University of Texas at Dallas (UTD) nanotechnologists and an Australian colleague have produced transparent carbon nanotube sheets that are stronger than the same-weight steel sheets and have demonstrated applicability for organic light-emitting displays. view more (2005-08-19)
Paperwork: Buckypapers clarify electrical, optical behavior of nanotubes
Using highly uniform samples of carbon nanotubes-sorted by centrifuge for length-materials scientists at the National Institute of Standards and Technology (NIST) have made some of the most precise measurements yet of the concentrations at which delicate mats of nanotubes become transparent, conducting sheets. view more (2008-10-16)
Detection of DNA on nanotubes offers new sensing, sequencing technologies
Researchers at the University of Illinois at Urbana-Champaign who recently reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to target specific DNA sequences. view more (2006-02-22)
Nanotube Adhesive Sticks Better Than a Gecko's Foot
Mimicking the agile gecko, with its uncanny ability to run up walls and across ceilings, has long been a goal of materials scientists. view more (2007-06-20)
Rare radio supernova in nearby galaxy is nearest supernova in five years
The chance discovery last month of a rare radio supernova - an exploding star seen only at radio wavelengths and undetected by optical or X-ray telescopes - underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. view more (2009-05-28)
Mysterious energy burst stuns astronomers
In a shock finding, astronomers using CSIRO's Parkes telescope have detected a huge burst of radio energy from the distant universe that could open up a new field in astrophysics. view more (2007-09-28)
Frantic activity revealed in dusty stellar factories
Thanks to the Very Large Telescope's acute and powerful near-infrared eye, astronomers have uncovered a host of new young, massive and dusty stellar nurseries in nearby galaxy NGC 253. The centre of this galaxy appears to harbour a twin of our own Milky Way's supermassive black hole. view more (2009-01-21)
Physicists and engineers search for new dimension
The universe as we currently know it is made up of three dimensions of space and one of time, but researchers in the Department of Physics and the Department of Electrical and Computer Engineering at Virginia Tech are exploring the possibility of an extra dimension. view more (2008-03-11)
Arecibo joins global network to create 6,000-mile telescope
On May 22, Arecibo Observatory in Puerto Rico joined other telescopes in North America, South America, Europe and Africa in simultaneously observing the same targets, simulating a telescope more than 6,800 miles (almost 11,000 kilometers) in diameter. view more (2008-06-11)
NASA Balloon Mission Tunes in to a Cosmic Radio Mystery
Listening to the early universe just got harder. A team led by Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md., today announced the discovery of cosmic radio noise that booms six times louder than expected. view more (2009-01-08)
MIT researchers fired up about battery alternative
Just about everything that runs on batteries - flashlights, cell phones, electric cars, missile-guidance systems - would be improved with a better energy supply. But traditional batteries haven't progressed far beyond the basic design developed by Alessandro Volta in the 19th century. view more (2006-02-08)
Optical Solution Revives Hands Free Mobile Telephones
Hands free sets for mobile phones may be on the verge of a big comeback thanks to new research by the University of Warwick. Many people used hands free sets in an attempt to avoid what they perceived as a microwave radiation risk from holding a mobile phone close to one`s head. However when it was pointed out that the standard wire based hands... view more... (2002-09-02)
Random antenna arrays boost emergency communications
First responders could boost their radio communications quickly at a disaster site by setting out just four extra transmitters in a random arrangement to significantly increase the signal power at the receiver, according to theoretical analyses, simulations and proof-of-concept experiments performed at the National Institute of Standards and... view more...
